Verifiability

Tags that are approved are usually features or properties that an individual mapper can confirm to be correct or false. A tag is verifiable if independent users would make the same observation.

This means that statistical properties (like peak vehicles per hour on a road) and subjective content (reviews, rankings) are not included in OpenStreetMap. Temporary, historic or speculative future developments are also excluded.

One feature, one OSM element

A single real world object should be represented with one element only.

Syntactic conventions for new tags

There are some conventions about naming keys and values. Following them will help mappers to estimate the meaning of your tags without reading the documentation. Using a semicolon should be considered especially carefully.
